Archived - Macintosh: Support for External Floppy Drives

I want to use two Apple 90 mm (3.5-inch) external floppy drives with my Macintosh. I have tried to chain them together, but the system recognizes only the first drive in the chain. Can I use more than one external floppy drive?

No Macintosh computer can work with more than one external floppy drive. Only the Macintosh SE and later computers can work with the Apple SuperDrive (Apple FDHD).

Notes:
    1. Floppy disk drives on some PowerBook computers are optional.
    2. Some Apple computers that do not have a floppy disk drive, like an iMac computer, work with optional external floppy disk drives connected to the Universal Serial Bus (USB) port.
